Wherein, the outer end (or claiming tail end) of at least one blade 20 is formed as bifurcation structure, and bifurcation structure can improve heat radiation
Effect.Specifically, during washing machine work, the deficiency in draught that the fan blade of prismatic blade type produces is to take away motor surface in time
Heat, such long-play, it is easy to cause heat build-up, cooling-down effect is poor.And at the wind of the embodiment of the present invention
Impeller 100 is under motor shaft drives during operating, and the fan blade 100 with air vent 102 can promote wind direction to change
Becoming, airflow direction flows up through motor surface from fan blade 100, and bifurcation structure can strengthen the pressure in this region so that tail
The air-flow of end is more easy to gather to inner side and flow up, and the pressure without tail end as prismatic blade is relatively small, air-flow
Easily form broadband sound source to outer rim, cause air quantity to reduce.Therefore, the fan blade 100 with bifurcation structure can increase and blows to
The air quantity on motor surface, makes the radiating effect of motor for washer 200 promote.
This structure no longer uses traditional blade that increases to realize the technological means that air quantity increases, but have employed a kind of new technology
Design, achieves the lifting of air quantity on the premise of not increasing fan blade quantity, can effectively save material usage, reduce into
This, manufacturability is strong.
Fan blade 100 according to embodiments of the present invention, by the outer end of blade 20 is designed as bifurcation structure, can increase and blow
To the air quantity on motor surface, the lifting radiating effect to motor for washer 200, and it is increased without the quantity of blade 20, material
Material consumption is less, and cost is relatively low, practical.
For ensureing preferable radiating effect, preferably, the outer end of each blade 20 all can be formed as bifurcation structure.Thus,
Being blown to the wind on motor surface be more uniformly distributed and air quantity is more, the lifting of radiating effect is the most notable.
